Hi, Thanks for your reply. I am sorry to give you a whole lot of explanation below,
NAT box set up is done with the iptable commands iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE This works good if I browse or if connect to internet from the behind nat windows pc. So I thought the same is enough and so I didn make any changes in the captures with respect to tcpreplay. I just pumped the traffic I already captured using tcpreplay in the nat box eth0 interface. Still the traffic is not received by the behind nat windows pc. Any small help is really appreciable. Regards S.

And read any logs on the NAT box.
